https://github.com/apache/zookeeper/pull/178
As per the offline discussion with @afine, identified that `checkstyle ant
task` is not working in branch-3.4 and will be raising a new jira task to
correct this.
```
checkstyle.check:
set-checkstyle-classpath:
checkstyle:
[checkstyle] log4j:WARN No appenders could be found for logger
(org.apache.commons.beanutils.BeanUtils).
[checkstyle] log4j:WARN Please initialize the log4j system properly.
[checkstyle] log4j:WARN See
http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.
BUILD FAILED
$ZK\git\b-3-4-new\build.xml:1595: Unable to create a Checker: cannot
initialize module PackageHtml - Unable to instantiate PackageHtml
```
Thanks @afine for the patience. +1 for the simple fix. I will merge this PR
to branch-3.4, tomorrow if there is no objection from anyone.
